I've successfully generated the TypePlugin and TypeSupport classes, compiled and linked them to my application.From the earlier posts, I understand that due to name mangling, we neet to prefix the topic names in DDS nodes with "rt/" in order to make them visible on ROS2, which I also did. This updated version includes the changes in data type nesting and naming, for example: An earlier type definition might look like this: module std_msgs { module msg { struct Bool { boolean data; }; };}; module std_msgs { module msg { module dds_ { struct Bool_ { boolean data; }; }; };}; Note the added layer of nesting under "dds_", and the trailing underscore on the struct name "Bool_".This matches the types that are generated in the ROS2 build system.
